Across the avian lineage, closely related species, or even populations within the same species may display differing migratory phenotypes. The many components of migratory behaviour are inherited as one migratory gene ...
Effects of marine protected areas and selective fishing on abundance, age and size structure of goldsinny wrasse (Ctenolabrus rupestris) populations. Restricted Access
(Master thesis / Masteroppgave, 2015)
Wrasse species went from having almost no commercial value in Norway, and not being fished, to a landing of 21.2 million individuals in 2014 with 11.68 million of these being goldsinny. This explosive growth in fishing ...
